Analysis of GB grid carbon-intensity for 2009 finally done...

[DamonHD]

I finally updated my page (see cluster of graphs at the end) with an analysis of grid intensity for GB (UK excluding Northern Ireland) for the whole of 2009:

http://www.earth.org.uk/note-on-UK-grid-CO2-intensity-variations.html

The interesting points are that:

1. The is an average (carbon/emissions) saving of ~25% to be had by load-shifting, which if nothing else corresponds to the saving from avoiding use of pumped storage.

   
   

2. There is currently a far smaller (relative) saving to be had in winter since the relatively fixed amount of zero/low carbon fuels is drowned in fossil when keeping up with winter demand.

Looks really interesting and a lot of hard work!

Will spend some time to look over it tomorrow morning. Thanks Damon

DamonHD,

Since the global warming/climate change has been shown to be a fabrication I assume your doing this to see how much power can be saved?

If time of day power generation has cost associated to it then the time of day cost should be passed on. To save 25% in my power bill I will shift when I use the power. If it does not save me a dime then I will put no effort nor expense. Why would I?

Have fun,

Scott.

I am absolutely doing it to save carbon emissions and don't accept your "fabrication" assertion.  This doesn't save any energy per se.

However, the argument about load-shifting reducing infrastructure costs and eliminating use of the more expensive peaking plants still stands.  Your electricity can cost less overall if you do it, especially if the utility exposes their wholesale savings though a dynamic time-of-day tariff as many the US already do, for example.

Damon,

I would be glad to review the IPCC documents in detail.

Using the original undoctored documents they cite.

Interesting starting point: http://www.canadafreepress.com/index.php/article/6855

Questions to ask:

How many working on the IPCC panel have climatologist backgrounds?

Who wrote the IPCC summery?

What is the background of the IPCC chairperson?

Have fun,

Scott.

This does look like fun I'll take some time with your data and see what is cooperative with some locale numbers .Thanks

Erected this morning from roughly one quarter of the 8-10 inches of global warming fallout that dropped on my driveway yesterday and this morning and standing at 6'6" tall, this is Mt. Anthropogenic.

Also known as Chicken Little Peak.

Curse you Zap! I just spewed egg roll all over my monitor!

Sorry Volvo... I never like to see perfectly good egg roll spewed... especially on sensitive electronics.

One of the things that no body wants to talk about is how sea water will affect the ground water once it invades the main aquifer . I see the minerals all over everything along the coast .

Imagine a town supplied by hydro. The dam produces enough for the whole town on the weekends, but only enough for the businesses during the work week. Lets say during the work week the homes are powered by coal instead, because it's imported cheap. The more energy they use during peak hours, the more pollution they're responsible for.

Very much simplified, but you can see how using energy during peak hours is bad...

In this case, every little bit of energy the homes use during a work-day is from a dirty source. If they shift all their loads to off-peak hours then it would be a green oasis. But, some people stay home doing laundry, vacuuming, etc...for us guys that's pressure washing the boat or making a tool to make a tool that makes a tool.

Pollution is bad by definition, whether you believe in global warming or not.

[DamonHD]

Well indeed; burning coal also pumps Mercury, Uranium and other toxic goodies into the atmosphere, in smaller amounts per kWh in places with tight emission controls enforced.

Damon;

 Jumping in here a bit late, but did want to say the link IS very interesting to read.

The colored graphs help to point out the overload of the grid during the home hours in the middle of the day, And looking at the data... it looks like it's getting even more loaded.

Thanks for the link, It will be interesting to see how 2010 a full year looks.

Cheers
